Hello everyone and a Happy Easter...

I've poking around the Tastrade example in VFP3b trying to learn (again).

I've found some variables or definitions that I'm not quite sure where they are defined or if they are part of VFP3b language.

For instance.
they use the message box like this:

=messagebox(MESSAGE_LOC,MB_ICONEXCLAMATION,'TITLE_LOC')

Would someone tellme where do they get: MB_ICONEXCLAMATION?

And what does the _LOC at the end means? (I assume local) but just want to be sure.

Is MB_ICONEXCLAMATION part of the syntax for messagebox or is it defined somewhere?

Thanx to all for your help.

Alfred.
